The factors that affect vital capacity are :
- Age
- Sex
- Height
- Body mass
- Ethnicity
Explanation:
Vital capacity is the maximum amount of air that a person can exhale once he has filled his lungs with maximum air. So, it is like maximum exhalation after maximum inhalation by a person.
Vital capacity is also equal to Forced Vital Capacity.
Lung usually have their maximum capacity in early adult days and this capacity reduces as the person grows older. So age is the prime factor in this.
A female with same age and height as that of male will have 10-12% less vital capacity than him. So sex is another reason which determines vital capacity.
Person with more height has more vital capacity. This is because lungs capacity is closely related to the third power of person's height.
Person suffering from obesity will have compressed diaphragm, lung and chest cavity , so their vital capacity will be less. So we can say body mass affects vital capacity.
Last factor, ethnicity, is yet to be understood clearly as there is not much evidence of this.
Answer:
Normal force may be less than weight, if there is some force with a component that acts opposite to the weight force. ... If the pulling force is horizontal, on a horizontal surface, then the normal force is equal to the weight. This is something your chould be able to see from a free-body diagram
Explanation:
Answer:
A; the reason why a balloon stuck to the wall was that it was electrically charged (negativly). when you put it by the wall it pushes the negative particles in the wall away and pulls the positive particles closer so that it sticks to them.
B; the reason for this is because of gravity. according to Einstein's General Theory of Relativity gravity is warpiture in spacetime which makes mass fall towards other mass.
C; this is because as the amount of oxygen in the air decreases and the air becomes drier, blood vessels inside your nose can crack and bleed. as you get higher the amount of air becomes proportionally less because there is less gravity to hold it down to the earth.
D; this is because the tallest buildings way a tone or many many tones which creates a lot of pressure where it sits. the reason they have wide foundations so that the pressure is spread out.
E; anyone who is around different amounts of air and different amounts of pressure will need a special suit so that their bodies can function as they would in their normal environment.
F; the bottom of a dam needs to be much stronger than the top because all of the pressure from the water on top gets channeld to the bottom.
